Like Indy's O-line, the cornerback squad has declined into chaos since the superbowl and hasn't really found itself. Vontae Davis was a fantastic move – when he's healthy. Letting Tim Jennings leave was another fantastic move. Hopefully, picking up Greg Toler will be enough to finally cement Indy's pass defense (along with Bethea and Landry). Meanwhile, Josh Wilson has the Stampede Blue cornerback preview.
The biggest success of the cornerback position last year, however, was Darius Butler. Signed by the Colts on September 25, Butler would play in 11 games for the Colts in 2012, starting 4. He notched 31 tackles, 7 pass deflections, 4 picks, 2 touchdowns, 1 forced fumble, and 1 fumble recovery. Butler was a huge part of the Colts' playoff run and was rewarded when the Colts re-signed him this offseason, a move that I was very certain should happen.
Bulter might be a good nickel-guy, but I can't see him accruing decent playing time unless the Colts get plagued by injuries this year. If the 5th year DB is starting games mid-season, something has clearly gone wrong (and let's pray it isn't Vontae Davis again).
